WARPING-MACHINE.

Specification of Letters Patent.

Patented Jan. 11, 1910.

Application filed May 5, 1909. Serial No. 494,170.

To all whom it may concern:

Be it known that I, CLARENCE A. STEERE, a citizen of the United States, residing at Providence, in the county of Providence and State of Rhode Island, have invented certain new and useful Improvements in Warping-Machines, of which the following is a specification.

My invention relates to warping-machines, so-called, and it consists in certain novel devices associated with and forming a component part thereof, all as more fully hereinafter set forth and claimed.

The object sought to be attained is to greatly increase the efiiciency and output capacity of warping-machines. That is to say, to position and mount the cops and guide the several threads leading therefrom to the warp-beam on which they are to be wound so that the threads will readily render to draw off from the cops with much greater rapidity and a more uniform de gree of tension and at the same time with less liability of breaking, as compared with warping-machines heretofore devised.

Among the devices employed in my improved warping-machine to accomplish the advantages just referred to are the following: to provide readily manipulated means for removably securing the cop non-revolubly and horizontally upon an arbor or copholder, thereby adapting the thread to be drawn from the free end of the cop; means adapted for removably securing the arbor to a standard or frame; a checking or braking device to prevent the thread from being drawn too freely from the cop, whlle at the same time subjecting it to a proper degree of tension, and guides adapted to prevent the threads of adjacent cops from excessive ballooning and interference with one an other while they are being rapidly drawn from the outer or free end of the thus held stationary cops.

In-the accompanying sheet of drawings, Figure 1 represents a front end elevation of a warping-machine embodying my improvements. Fig. 2 is a horizontal or plan sectional view taken on line 00 w of Fig. 1. Fig. 3 is a partial plan view of the warpbeam, somewhat enlarged, showing a series of cop-threads connected therewith. Fig. l is a partial front elevation, partly in section and in enlarged scale, showing the combined brake and tension device for controlling the thread. Fig. 5 is a horizontal sectional view of the cop-supporting frame or standard showing a cop-holder mounted therein, the cop itself being omitted. Fig. 6 is a partial side elevatlon of the said frame member, as adapted to receive the cop-holder. Fig. 7 is a detached plan view of the arbor or cop-holder, and Fig. 8 is a central longi tudinal sectional view, enlarged scale, taken through the outer end portion of the arbor.

I would state in advance that the main winding mechanism proper of the warpingmachine A, represented in Fig. 1 of the drawings, is well-known and I therefore make no claim to the same, except as combined with certain elements or devices hereinafter described. The said machine is provided with a reed Z) through which the segregated threads t are simultaneously drawn from the stationary cops and wound in the usual manner upon the barrel of a revoluble beam or flanged spool a.

B, designates a vertical stationary cop supporting frame comprising the tubular post or pipe 79 and the tension-supporting member (Z. The post member is provided throughout its length with a series of uniformly spaced horizontally disposed parallel holes 39 Fig. 6, each adapted to receive the hollow stem or shank e of the cop-holding arbor E; the latter having a handle part 6 a collar 6 at the base of the handle, and a fixed pin 6 This pin passes transversely through the shank and projects therebeyond, as represented in Fig. 5. Said pin is located with relation to the collar sothat when the shank is inserted to its limit in the corre sponding hole 10 of the hollow post, as determined by said collar, and the arbor turned axially about 90 the ends of the pin will then engage or wedge themselves against the adjacent inner concave surface of the posts wall and cause the collar to bear snugly against the outer side of the post thereby firmly locking the arbor in position. It may be added that slots p Fig. 6, extend from the pole p in opposite directions through the wall to permit the free passage of the pin 6 The inner or free end portion of the hollow arbor is provided with a pair of op positely disposed narrow longitudinally extending slots (2 and a fixed transverse pin r. Upon the latter is mounted a length of helically wound resilient wire 8 having its free end portions bent to form crossed arms s which extend rearwardly within the arbor, as clearly shown in Fig. 8. The said arm members are further bent to serve as springs 5 adapted to normally extend through the respective slots 6*. As thus devised the springs readily yield during the introduction of the arbor into the post and immediately thereafter return to the expanded or normal position. After the arbor is locked in place as before described, it remains practically rigid so that the cop 0 may be readily mounted thereon, assuming that the bore of its quill or tube is the same or slightly greater than the diameter of the arbor, the pressure of the springs then causing the latter to frictionally bear against the quill and hold the cop stationary thereon, thereby pre venting both endwise and axial movement.

Each thread it passes from the free end of its stationary horizontally mounted cop 0 to and between a pair of laterally separated light vertical guide-wires c to a device, I),

adapted for controlling the tension and also for preventing a too free unwinding of the thread; the latter then passes through a fixed guide-eye 2' and the reed b and is wound upon the revoluble beam a.

The device, D, is supported by a horizontal bracket (Z in turn secured to the said upright member (Z, see Fig. 4t. A fixed stud (Z extends upward from the inner or free end of the bracket and is provided with a loose bottom washer to. A thin fiat sheetmetal freely revoluble disk h, resting upon the washer, has an annular central hub if on its upper side through which the stud (l project-s. Upon said disk rests a flat revoluble fellow disk member 71 having the said hub extending through it. The adjacent faces of the disks are maintained in normally light frictional contact with each other by means of the expansive force of a suitable superposed spring g. The outer edges or rims of the disks may be curved in opposite directions, as indicated at f, so as to form a continuous flaring entrance for readily guiding the thread between the disks. As thus constructed the free movements of the traveling thread passing from the stationary cop is or may be checked or retarded to some extent while it is being drawn between the disks by the revolving beam, thereby at the same time equalizing the tension upon the thread, and also serving to remove from it any loose fibers or light foreign matter. I deem it advisable to so guide the thread that when in use it will draw against the periphery of the adjacent portion of the hub, it, and cause both disks to rotate, although not necessarily in unison with each other.

Located in front of the free ends of the cops are positioned two parallel laterally separated vertical rods, 0 0 the distance between them exceeding say the diameter of a full or loaded cop 0; these rods and the light vertically spaced horizontal wires 0 connected to them and located between the cops, see Figs. 1, and at, serve when the machine is in action to prevent the traveling threads from excessive ballooning The cops are first mounted and frictionally held stationary upon the previously positioned arbors E, as before described, and the free ends of the threads passed between the vertical guide-wires (1, followed by introducing the threads between the disks of the respective devices D and into the corresponding stationary guide-eyes i, Fig. 2; from the latter the threads extend in a converging manner to the usual reed Z) and onto the barrel of the winding beam at.

I claim as my invention and desire to se cure by United States Letters Patent,-

1. In a warping-machine, the combination with a metal post having annular alls and a series of suitably spaced holes extending transversely therethrough, of a shouldered cop-holder having a shank or arbor adapted when in use to be seated in said hole and extend beyond the post, and a pin or lug integral with the arbor adapted upon turning the holder a partial revolution to engage the adjacent inner surface of the wall in a wedge-like manner for locking the holder in position.

2. In a warping machine, the combination of a vertical stationary frame, a plurality of relatively stationary cop-holders ar ranged above one another in horizontal planes removably seated in said frames, a combined thread-retarding and tension device located forwardly of each cop-holder and being in substantial alinement with its axis, a pair of laterally separated stationary vertical guide members located between the forward end of the cop-holders and said tension devices adapted when in use to lead the respective threads into the latter, and means for winding the threads upon a beam.

3. In a warping-machine provided with a vertical post or standard and a plurality of normally stationary horizontally disposed cop-holders removably seated therein, the combination therewith of a pair of stationary laterally separated vertical guide-rods located forwardly of the free ends of said holders, a plurality of stationary horizontal guide members spaced and arranged above one another and located intermediate said guide-rods and cop-holders, and tension devices adapted when in use to receive therein threads passing from cops mounted on said holders, the threads first passing between the said horizontal and vertical guide members.
